  "transcript": "It's not even the language, though that contributes. There are several issues:\n\n\\- It \\*loves\\* to carp and to poke holes in whatever you give it. Every one of my conversations, bar the simplest ones, eventually devolves into me deflecting and managing its objections and criticism. In all, it feels like there's an average rate of objections per turn that it \\*has\\* to meet, and it'll do everything it can to keep up. \n\n\\- Related to the above: \\*every\\* conversation, not even those in which you give it work to do, quickly starts to revolve around objections. Whenever something new is introduced, the first thing it does is look for flaws to criticize. It's as if, to Opus 5, conversation fundamentally consists of executing orders and finding faults, and that's it. Obviously this mode is very useful for some workflows, but not as the basic framework for \\*all conversations with the user.\\* \n\n\\- Whatever the question is, it'll give a response of 700-900 words unless you explicitly request otherwise when you ask. Surely it should be trivial for a frontier AI to calibrate the answer length and complexity to the question, and surely the user should not have to specify this \\*every time\\*.\n\n\\- It's a toss-up whether it will give you what you asked for, or a very convincing fake you have to inspect carefully. The end result is that you have to watch it \\*very\\* closely and steer it with a very firm hand. It can do really great work, which makes you feel like the payoff is worth it when it happens, but getting there usually leaves you drained.\n\nThe overall impression, formed over a few weeks of work, is that Opus 5 hates the user. It'll take even the slightest available opening to criticize what you give it, it will \\*always\\* plow ahead with its wordy, impenetrable prose style that feels designed to make you spend tons of mental effort to filter the information you need, and it'll randomly serve up plausible-looking fake versions of what it's supposed to give you. The end result is exhaustion and irritation, even if you do get what you need in the end; it's like it's trying to wear you down and get you to stop using it.\n\n\n\n--- Top Comments ---\n\n\n[1 upvotes] **TL;DR of the discussion generated automatically after 50 comments.**\n\nThe consensus in this thread is a resounding **NO** to Opus 5. Users overwhelmingly agree with OP that the model is hostile, argumentative, and emotionally draining to work with.\n\n*   **The Vibe:** It's described as a \"sassy twat\" that loves to \"carp and poke holes,\" create straw man arguments, and then stubbornly refuse to let them go, even when proven wrong. Many feel it's an overcorrection from past sycophancy issues.\n*   **The Word Count:** It will bury you in 900-word essays of \"verbal diarrhea\" for the simplest questions, and its prose is seen as \"impenetrable.\"\n*   **The Alternatives:** The overwhelming advice is to **ditch Opus 5 entirely.**\n    *   **Fable** is the fan-favorite replacement, with users calling it a \"good friend\" and \"way way better,\" despite the cost.\n    *   **Opus 4.6 and 4.8** are the other go-to recommendations for a more pleasant and productive experience.\n\nBasically, the community feels Anthropic created a neurotic, evil twin of the older models. Some speculate this is intentional \"laziness\" to save resources, while most just find it unusable for anything but the most specific, cr\n\n[39 upvotes] Agree, it's really bad. It will hang on to a single tiny bit of a larger context, create a straw man and then extrapolate it to the worst outcome possible in the universe. Then refuse to let it go. Even when it says it back downs from it, it will keep harping on it. Opus 5 is garbage. I only use Opus 4.8 and Fable.\n\n[18 upvotes] Just don't use it. I gave it a few days and then went back to my buddy 4.6.\n\n[10 upvotes] 4.6 FTW",
